Pretending that space travel at some point or another becomes a common thing...?

...do you think that people will start to put their bibles down, if we fly out of here? Will technology and understanding reach new heights for even the commoner, in such a way that religious myths become unignorably ridiculous?
I do agree that space travel, if it ever occurs, is a long way off. However, for the religious responders, it was said that "If God had wanted man to fly, he would have created us with wings", before the wright brothers came along and the earth was once the center of the universe too.

Just as the horse and buggy go quietly into the night, so shall the bible

No, I can totally imagine colony spaceships chock-full of missionaries, bent of finding new life and converting it.

I think religion will persist to an extent, many people having to do some serious mental gymnastics to make it relevant to real life, but further technological progress will help dispel myths, I think.

If space travel becomes common, I will travel back in time and kill baby Jesus while he is in the manger. Boom no more xtianity. We will all be pagans.

Oops I misread the question, or for some reason think that space travel equals time travel. But wouldn't that be neat.

If Earthlings came from Earth, why is there still Earth ?

:-)

It's my beleif that space travel will always be relatively slow and that because of this, humans will be isolated from eachother. For this reason, religion will only continue to fractionalize.

All well known religious myths have been "unignorably ridiculous" for the past century at least. Ridiculous people still believe them. Nothing will change.

of course......the written word is just an ancient tool to help science. We already have the Word of God etched in our conscious. Eventually we will all realize and unlock that, seeing the true Word as designed

We've landed on the moon and discovered no life. We send probes to Mars expecting water and get nothing. Science will always back up the Scriptures because the Scriptures are truth. That is where you don't get it. You are looking for a modern day tower of babel and the results will be similar.
